Blastula stage; Information: After the morula stage the blastomeres spread and build a monolayer of cells around a central cavity (the blastocoel, bc). This stage is called the blastula stage ... Webblastocyst, a distinctive stage of a mammalian embryo. It is a form of blastula that develops from a berrylike cluster of cells, the morula. A cavity appears in the morula between the cells of the inner cell mass and the enveloping layer. This cavity becomes filled with fluid.

WebThe early stages of embryonic development begin with fertilization. The process of fertilization is tightly controlled to ensure that only one sperm fuses with one egg. After fertilization, the zygote undergoes cleavage to form the blastula.
